Voyage time by boat speed
Time underway is distance divided by speed. These are continuous-passage figures with no stops or weather margin.
| Boat and speed | Time underway |
|---|---|
| Sailboat, conservative (5 kn) | 39d 6h |
| Sailboat, average (6 kn) | 32d 17h |
| Displacement trawler (8 kn) | 24d 13h |
| Fast trawler (10 kn) | 19d 15h |
| Planing motor yacht (15 kn) | 13d 2h |
| Fast motor yacht (20 kn) | 9d 19h |
Planning estimate, not navigation
This distance is computed over the open Eurostat shipping-lane network. It is a realistic passage length for planning, but your sailed distance will differ with weather routing, currents, draft, and the exact berths you leave from and arrive at. Always verify against official charts.

Plan this passage properly
Open Barcelona to Mombasa in the Marine OS route planner: it suggests the sea route, then you drag waypoints, set your speed and fuel burn, and check weather and tides along the way.

How far is Mombasa from Barcelona by sea?
About 4,708 nautical miles (8,719 km / 5,417 statute miles) along the practical sea route, which transits Suez Canal and Bab-el-Mandeb. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.

At a typical sailing average of 6 knots it is about 32d 17h underway. A 10-knot trawler needs about 19d 15h, and a 20-knot motor yacht about 9d 19h. Add margin for weather, currents, and stops.
How is this distance calculated?
It is computed over the open Eurostat global shipping-lane network, the same kind of network freight routing tools use. It is a realistic planning estimate, not a navigation product: your sailed distance will vary with weather routing, draft, and the exact harbors you use.
